<p>Hey folks, I'm working on updating the "type inference variables" section on the rustc-dev-guide, here's the current: <a href="https://rustc-dev-guide.rust-lang.org/type-inference.html#inference-variables">https://rustc-dev-guide.rust-lang.org/type-inference.html#inference-variables</a><br>
it says we have <strong>four</strong> variables but if my understanding is correct, we also have const variables after <a href="https://github.com/rust-lang/rust/issues/59008">#59008</a>, right? I guess it's the only part to update but if there is anything I've missed, please let me know, thanks!</p>

<p>I've created a PR for it: <a href="https://github.com/rust-lang/rustc-dev-guide/pull/1145">https://github.com/rust-lang/rustc-dev-guide/pull/1145</a><br>
I'd appreciate it if someone familiar with the area reviews it :)</p>
